SCAFFOLD- BRACKET.

SPECIFICATION forming part of Letters Patent No. 457,949, dated August18, 1891.

Application filed October 23; 1890. Serial No. 369,055. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE E. BENTON, a

- citizen of the United States, residing at Monroe, in the county ofOrange and State of New York, have invented a new and usefulScaffold-Bracket, of which the following is a specification.

This invention has relation to scaffoldbrackets for use upon roofs ofvarious pitches; and the objects in View are to provide an adjustablebracket adapted to be applied to shingle roofs and adjusted inaccordance with the pitch thereof so as to support a platform in ahorizontal position, regardless of such pitch; furthermore, to obviatethe use of spikes and nails or other devices liable t injure the roof.

Various other objects and advantages of the invention will appear in thefollowing description, and the novel features thereof will beparticularly pointed out in the claims.

Referring to the drawings, Figure 1 is a perspective of a bracketconstructed in accordance with my invention, the same being applied to ashingle roof. Fig. 2 is a longitudinal section of the bracket.

Like numerals of reference indicate like parts in all the figures of thedrawings.

In practicing my invention I construct the entire bracket, with theexception of the setscrews and necessary rivets, of spring sheet-- steelof sufficient thickness.

1 designates a substantially L- shaped frame formed of a strip of springsheet-steel, and comprising the upper horizontal supporting-terminal 2and the Vertical terminal 3. The vertical terminal 3 is shorter than thehorizontal terminal, and is provided with a series of holes 4, wherebyit is adj ustably connected by a screw 5 to the upper end of a section 6of the vertical terminal, which lat ter is provided at its upper endwitha pair of keepers 7, which overlap the edges of the upper section orterminal, and at its lower end is notched to form spurs or spikes 8. Byadjusting the screw 5 the vertical terminal may be lengthened orshortened, and it will be observed that said terminal, in connectionwith the section 6, constitutes a supportingstandard for the horizontalterminal 2. The

horizontal terminal is provided at intervals with raised spurs ortongues 9, designed to engage .with a wooden platform or plank laidthereupon, and at its extremity said terminal has hinged thereto, as at10, an L-shaped foot 11, the extremity of which is rounded and beveled,as at 12, whereby it is adapted to be inserted under a shingle.

12 designates a diagonal brace, and the same consists of a V-shapedsection 13, at the upper end of the brace, andalower U-shaped section14. The outer branches of the two sections are perforated, as at 15, andare ad j ustable, the upper upon the lower by means 1 of a set-bolt 16.The branch of the lower sectionis provided with a pair of oppositekeepers 17, which embrace the opposite edges of the upper section andmaintain the two sections in sliding contact. The inner branch ofthe'upper section is provided at its lower or inner terminal with aVshaped notch, forming spurs 18 for engaging with the shingles, whilethe lower or inner branch of the lower U-shaped section has itsextremity rounded and beveled, as at 19, and adapted to be insertedunder the shingle below the one under which the foot 11 is inserted.

It will of course be understood that two brackets constructed asdescribed are employed, and by operating the screws 5 and 16 theproportions of the brackets may be varied so as to agree with thevarious pitches of various roofs, and thus always support the platformor plank in a proper horizontal position. The two spurs 8 and 18 of theupper section 13 and lower section 6 serve to prevent any downwardslipping upon the part of the bracket, while the foot 11 and lowerterminal 19 of the lower section let serve to prevent the bracket fromrising or lateral movement.

Having described my invention, what I claim is 1. The herein-describedbracket, consisting of an inverted-L-shaped frame having the rear orvertical extensible member or terminal, and the hinged foot engaging theupper terminal and adapted for insertion under a shingle, substantiallyas specified.

2. The herein-described bracket, consisting I00 of the inverted-L-shapedframe formed of sheet-steel, the horizontal terminal of which isprovided at its front end with an L-shaped foot hinged thereto andhaving a front bev- 5 eled end, and the rear member or terminalperforated and adjustably connected by a bolt to an extensible sectionterminating in spurs, the U-shaped section l t, riveted to the lower endof said section and having its [0 lower terminal rounded and beveled totake under a shingle and its upper terminal perforated, the upperV-shaped section having its upper terminallikewise perforated, and anadj usting-b0lt connecting the two sections,the lower terminal of saidupper section being provided with spikes for engaging the shingles,substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two Witnesses.

GEORGE E. BENTON.
